Question

3 7/4 * (-1,4)
-3/11:(1 5/22)
/ это дробь

Answer 1

$1) 3 frac{7 {}^{(25} }{4} times ( - 1.4) = 3 + frac{175}{100} times ( - 1.4) = 3 + 1 frac{75}{100} times ( - 1.4) = 4.75 times ( - 1.4) = - 6.65 = - 6 frac{65}{100}$

$2)- frac{3}{11} div (1 frac{5}{22} ) = - frac{3}{11} div 1 frac{5}{22} = - frac{3}{11} div frac{27}{22} = - frac{3}{11} times frac{22}{27} = - frac{3 times 22}{11 times 27} = - frac{66}{297} = - frac{2}{9}$
